Cannot add Workstations to Windows Server Essentials


greetings, installed windows server essentials server , added 5 client machines without problem. subsequent attempts add machines result in error. "the server not available.". please contact administrator.  i attempted solutions on technet page problem no success. client deploy log displays following error: .5197: clientsetup: failed download setup.cab server: system.net.webexception: underlying connection closed: not establish trust relationship ssl/tls secure channel. ---> system.security.authentication.authenticationexception: remote certificate invalid according validation procedure.

i'm wondering first if there issue client cals. didn't see anywhere there limit, may have missed something. fact first 5 added without issue leads me think may case. in second case, how repair certificate issue if that's cause.

thanks,

steve

hi,

according description, understanding failed connect client windows server essentials, error "the server not available.".

>error "the server not available."
on client, make sure “tpc/ip properties - preferred dns server” configured essentials’ ip address. also, try connect client essentials server directly wired cable, , check result.

>i'm wondering first if there issue client cals.
in general, windows server essentials server, there user account , device number limitation. details number depending on system version. such as:
windows server 2012 essentials designed small businesses need support 25 user accounts , 50 devices.

mentioned there has been connected 5 devices, seems not related cals.

>the client deploy log displays following error: .5197: clientsetup: failed download setup.cab …validation procedure.
if problem happened on specific client device, except suggestions mentioned in above. try run “sfc /scannow” check/repair system files. restart system in clean boot, without 3rd process enabled. , try connect again check result.

if problem persists, please provide more information, such client os version, essentials server os version, related log file(complete log files).

if unable upload files via reply on forum, may upload file to onedrive (https://onedrive.live.com/) , share , provide me access link.


best regards,
eve wang
